DESCRIPTION

d2i_RSAPublicKey() and i2d_RSAPublicKey() decode and encode a PKCS#1
RSAPublicKey structure.
d2i_RSA_PUBKEY() and i2d_RSA_PUBKEY() decode and encode an RSA public
key using a SubjectPublicKeyInfo (certificate public key) structure.
d2i_RSAPrivateKey(), i2d_RSAPrivateKey() decode and encode a PKCS#1
RSAPrivateKey structure.
d2i_Netscape_RSA(), i2d_Netscape_RSA() decode and encode an RSA private
key in NET format.
The usage of all of these functions is similar to the d2i_X509() and
i2d_X509() described in the d2i_X509(3) manual page.

NOTES

The RSA structure passed to the private key encoding functions should
have all the PKCS#1 private key components present.
The data encoded by the private key functions is unencrypted and
therefore offers no private key security.
The NET format functions are present to provide compatibility with
certain very old software. This format has some severe security
weaknesses and should be avoided if possible.
